Not so.
I explained in the other thread (where you painfully demonstrated
your ignorance and misunderstading) where it comes from if we
assume light speed invariance. *That* is (at least historically) the
foundation.
If you accept  light speed invariance then you have no way out
from relativity of simultaneity.

Your understanding of it is false alright.
Just provide an experiment that shows that light speed
invariance is false. Then relativity of simultaneity no longer
follows from it and perhaps SR might collapse.

Yes, similarly.
Quite similarly :-)
